Abstract

The utility model discloses a battery connector centre, composed of a casing, a centre body, a bottom plug, and a spring. A tilt state is generated when the top end of the centre is pressed by a difference part which is arranged at the bottom end of the centre body, so the centre body abuts against the casing, and an electric current is conducted rapidly, thus increasing the conductivity while decreasing the resistance value effectively.

Description

The battery connector thimble

Technical field

The utility model relates to electronic product, is meant a kind of battery connector thimble that tilts to increase electric conductivity that utilizes especially.

Background technology

Habitual battery connector thimble as shown in Figure 5, be to be used for battery supplied electric energy conflict electric action, its structure is that two formula assemblies form, form jointly by a shell 10, a column needle body 12 and a spring 13 substantially, the inside of this shell 10 has the accommodation space 101 and a port 102 of a sealing hollow, insert accommodation space 101 backs and rely on its bottom at this spring 13, after making the inside of needle body 12 through being inserted in shell 10, will be subjected to the elastic force effect of spring 13, can in this accommodation space 101, slide up and down.

But this habitual thimble, because the accommodation space 101 of this shell 10 is an approximate enclosure space, one port 102 is only arranged, make when electroplating activity, entrapped air pockets is attached to the inner wall surface and the lower surface of accommodation space 101, causes and electroplates situation inhomogeneous or that be not electroplated onto, therefore is easy to occur the flaw and the defective of electric connection aspect, and then make as battery supplied electric energy conflict electric action the time, often find to have the problem of the not good or poor electrical contact of electrical conduction.

In addition, this habitual thimble, its conduction is to reach shell 10 by needle body 12 through spring 13, and spring 13 is many circles of coiled modes, its path is far away, thereby has increased the ageing of conducting.

Summary of the invention

The purpose of this utility model promptly is to overcome the above-mentioned shortcoming and defect of habitual battery connector thimble, thereby a kind of improved battery connector thimble is provided.

For achieving the above object, battery connector of the present utility model mainly is made up of shell, needle body, bottom plug and spring, enclosure has an accommodation space, insert needle body and spring in the accommodation space, bottom plug is arranged at the lowermost end of the accommodation space of this shell, and an end overhead of spring is in this needle body, and other end overhead is in this bottom plug, needle body is subjected to the overhead of spring and protrudes out an end outside shell, it is characterized in that: the position of needle body bottom overhead spring has the segment difference section.

Battery connector thimble of the present utility model, because the position of its needle body bottom overhead spring has the segment difference section, when needle body is subjected to external force when pressing down, this needle body will contract in will being tilted down, form needle body tilt to be resisted against shell first inwall, one side against locating, its electric current is passed on against locating through needle body by battery, again by against locating to conduct to circuit substrate through shell, thereby can make the rapid conducting of electric current.And because shell of the present utility model is an Open architecture, thereby when electroplating activity, electroplate liquid and can adhere to the shell surfaces externally and internally fully, do not have entrapped air pockets and be attached to the accommodation space surfaces externally and internally, and then cause and electroplate situation generation inhomogeneous or that be not electroplated onto.

Embodiment

By the technological means of further understanding structure of the present utility model, utilization promptly the effect reached of expection, now lifting several preferred embodiments and conjunction with figs. is described in detail as follows, believe the utility model creation purpose, feature and other characteristics, can obtain therefrom deeply and concrete understanding.

Please refer to Fig. 1～Fig. 4, the utility model mainly is made up of with bottom plug 40 and spring 50 shell 20, needle body 30, this shell 20 is to form by dashing the system of taking out, hollow tubular, inside has first, second and

third inwall

21,22,23 of different-diameter, and being contraction-like gradually from lower to upper, formation is the stair-stepping accommodation space 24 of hollow between each inwall, and first inwall, 21 internal diameters are less; Accommodation space 24 inside are provided with a needle body 30, this needle body 30 also protrudes out one section outside shell 20, and outer rim proximal end enlarged diameter edge forms a root edge 31, can form according to second inwall 22 of shell 20 and move up and down, and be stuck in first inwall 21 of shell 20, make this needle body 30 protrude out one section outside shell 20, but can not drop out; Have a segment difference section 32 at these needle body 30 root edges, overhead one spring 50, the other end of spring 50 then overhead can not be shifted in the bearing point 41 of this bottom plug 40.

It more than is the general introduction of structure, position and the interconnected relationship of each assembly of the utility model; Then, again with each combination of components of the utility model and expect the effect statement as the back of reaching:

Please continue 1～Fig. 4 with reference to figure, because needle body 30 is arranged at accommodation space 24 inside of shell 20, thereby the elastic force that is subjected to spring 50 is upheld and is convexedly stretched in outside shell 20 words, but the root edge 31 of this needle body 30 is stuck in 22 of first inwall 21 of shell 20 and second inwalls, make this needle body 30 protrude out one section outside shell 20, but can not drop out, form first inwall 21 that needle body 30 outer rims depend on shell 20, and the root edge 31 of needle body 30 depends on second inwall 22 of shell 20, two sections depend on the strong point, make needle body 30 overlap (as shown in Figure 3) with shell 20 same centers.

When needle body 30 is subjected to external force (battery) when pressing down, this needle body 30 contracts in born responsibility by spring 50 to be tilted down because of having segment difference section 32, as shown in Figure 4, form needle body 30 tilt to be resisted against shell 20 first inwall, 21 1 sides against locating A, its electric current is passed on against locating A through needle body 30 by battery, by conducting to circuit substrate (figure does not show) through shell 20, make the rapid conducting of electric current again against locating A.

Because root edge 31 bottoms of needle body 30 of the present utility model have a segment difference section 32, therefore when needle body 30 top pressurizeds, simultaneously during spring 50 1 end overheads, the state (as shown in Figure 4) that contracts in needle body 30 being produced be tilted to down, thus formation needle body 30 makes the rapid conducting of electric current against shell 20, but not with habitual identical, need via long spring 50 conduction in path, so the utility model can increase conduction and effectively reduce resistance value, this is one of major advantage of the present utility model.

Two of major advantage of the present utility model, be that shell 20 of the present utility model is Open architecture, it is when electroplating activity, the electroplate liquid body can adhere to shell 20 surfaces externally and internallies fully, no entrapped air pockets is attached to accommodation space 24 surfaces externally and internallies, and then cause the generation of electroplating inhomogeneous or the situation that is not electroplated onto, more can not occur the flaw of electric connection aspect and the scruple of defective, and make as battery supplied electric energy conflict electric action the time, it doesn't matter the problem of the not good or poor electrical contact of electrical conduction.

In addition, be convexly equipped with a bearing point 41 in the bottom plug 40 of the present utility model, but holding spring 50 be shifted with spring free 50 pressurizeds, have spacing effect, can be considered three of major advantage of the present utility model.
